' The member 21 of the ring shown in Fig. 6 is in reality a keystone forthe sections, as the two sections "17 and 18 are mounted so that theprojecting portion 25'Will enter the recess 4 in t e member 1, at whichtiune the member 21 is inserted from the center of the coupling and slidso that the portions at- 20 and 20f will slide into a tight fit with thesections 17 and. 18 at said points and the hooked lip 22 will pass intothe recess 5 of the member 1, at which time the entire sec.- tional.ring will be rotated so that the lip will assume the position as shownin Fig. 1, that is diametrically oppcljte to the recess 5 of the section1, thereby locking the parts in the desired position. I i g What isclaimed is:

1. A coupling having a sectional ring member, one of said sections beinga key I section to hold all the sections assembled withing'the coupling,and a hoolrcarried by said key sect-ion.

2. A coupling having a nut member with a concentric recess in one end,and an interior annular recess within the body adjacent said-end, and asectional key ring "adapted to fit in said interior annular recess andengage the concentric recess to'lock the sections within and to the nutmember.

3. A. sectional ring for couplings comprisin two segmental sections, anda key section, the end faces of all of said sections being parallel whenthe tin said key section having a 10c 'ng book.

1. A coupling comprising an outer nut member having a concentric recessin' one end, a channel leading radially thereinto, and an annular recesswithin the body thereof, a shouldered coupling member mounted in theother end of the nut member, a gasket is assembled, I

mounted withinthe casing and abutting said,

coupling member, a thimble member mounted from the oppositeeud androtatable with in the nut member, the inner end ofthe said thimblemember being provided with a carity to receive the gasket in oppositionto the coupling member, and a sectional ring for retaining the thimblenut member, comprising three end faces of'all'ot' which are semhledproviding a ring to lar recess within the nut member and having alocking means for entering theconcentric recess of the nut member.

In testimony that I claim the foregoing my own, I have hereto affixed mysignature in the prc-ence of two witnesses.
